Abstract
Description
I′(i,j)=B 0(i,j)+g 1(B 0(i,j))*B 1(i,j) +g 2(B 0(i,j))*B 2(i,j)+g 3(i,j))*B 3(i,j)
about the reference density. The reference density maps the log exposure value that will remain invariant when the slope of the tone scale is varied. The brightness control is used to shift the mean density of the image. The brightness control defines the log exposure code value that is mapped via the tone scale to the reference density.
also affects the dynamic range. According to the present invention, the lowest band is not manipulated for dynamic range control; instead, the slope of the tone scale is used. The dynamic range control is defined as the slope of the tone scale, dynamicRange=dD/dx at the reference density. Increasing the dynamic range reduces the latitude while decreasing the dynamic range increases the latitude.
and the gain term g1(B0(i,j)) affect the detail contrast, a detail contrast control is defined as a detailContrast(B0(i,j))=g1(B0(i,j))*(dD/dx).
g 1(B 0(i,j))=detailContrast(B 0(i,j))/dD/dx
g 2(B 0(i,j))=sharpness(B 0(i,j))*g 1(B 0(i,j))
g 3(B 0(i,j))=fineDetail(B 0(i,j))*g 2(B 0(i,j))
I′(i,j)=g 3(I 0(i,j))I(i,j)+(1−g 1(I 0(i,j))) I 0(i,j))I 0(i,j)+(g 1(I 0(i,j))−g 2(I 0(i,j)))I 1(i,j)+(g 2(I 0(i,j))−g 2(I 0(i,j))I 1(i,j)+(g 2(I 0(i,j)) −g 3(I 0(i,j))I 2(i,j)
